using a mauser barrell for a poormans m76

Now i have a virgin bulged yugo trunnion-no markings on it but its exact like a m70
Ive seen nice takeoff 8mm mauser barrels for sale and was wondering how difficult it would be to make it work

I still have to do some research on what bolt and carrier to use and stuff
But i think it'll work-I probably have to fold a longer reciever to make it work
I thought about a psl reciever but i think the dementions are way different
Oh and of course i'd have to make custom lower rails

Sounds like a fun venture in interchangability.
If you can fold your own receiver with extra length, then more power to you.

My initial impression on using 8mm in a stamped config, was that it had to be
the 1.6mm thickness.
I picked up a ColdSteel heavy yugo blank with extra length and converted a
Romy RPK kit into an 8mm rig. The recoil did hammer the rear trunnion loose
from the rivets. Some rework of rivets and welding the trunnion fast solved the
problem.

I found the 80% blank worked well because you can field all your layouts for the specific caliber.
Dimensionally, it is similar to the PSL receiver, because the cartridge lengths
are fairly close. I would not be afraid to convert a PSL receiver to 8mm. I think
the rail lengths are about correct, the magwell would need reworked.

If I remember right, the Mauser chamber threads would need to be turned down
and sleeved to get to the correct width for M70 trunnion. Otherwise, with some
mods, it's doable.

Go with the PSL bolt and carrier. The bolt face would need a sleeve to reduce diameter.

BTW, Green Mountain makes new M76 barrels.
I've tried one, and it's at least as good as the originals, if not better on accuracy.

Thanks for the info!
after thinking about it the mauser take off would cost me more in the long run-getting it turned and what not as opposed to the GM barrell which is the propper dimensions anyways
I diddnt think about the cold steel blanks-forgot they even had them-this is probably the way to go,as I'd have to make a jig to accomadate the leangth

As far as sleaving a psl bolt face what would be a good way to do it?
Or would just getting an m76 bolt and carrier be cheaper?
As far as the rear trunnion is concerened i could put streangthening plates on it and use longer rivets

Would i have to modify/tweak the bullet guide in the front trunnion for the 8mm?I probably have to anyway for propper mag fit clearence

For the bolt face, I would turn down a ring on my mini-lathe
and mig weld it in place. I've done this to AK bolt faces to convert to the
9mm cartridge. So, I think it would be fairly simple to do.

If you can find an M76 bolt and carrier then this would be the way to go,
however, seldom are spare parts found for these rifles.

The plates with longer rivets would probably do on the rear end.
Also, a stronger recoil spring takes some of the energy, I ended up swapping out
the AK spring for an M-14 spring, and this quieted it down also.

A build like this is tends to keep you awake at night. lol.
